摘要： A process is provided for improving sensory properties of essential oils by treatment and incubation with a microbial culture during the extraction process. A method for increasing the patchulol content in essential oil extracted from leaves of Pogostemon cablin is provided, comprising contacting a dried patchouli biomass with microbial cultures, incubating the patchouli biomass under conditions suitable for allowing the increase in the patchulol content and extracting the oil. This process results in increased patchulol content without decreasing the overall oil yields. The patchouli oil also has enriched aroma.

摘要： The present invention provides an efficient and improved process for the production and purification of high molecular weight hyaluronic acid (HA). One embodiment relates to providing growth conditions for production of high molecular weight HA in Streptococcus zooepidemicus. For example, growth in medium comprising a lower protein concentration, e.g., 1% casein hydrolyzate, and a higher sugar concentration, e.g., 5% sucrose, gave 5-6 g/L of high molecular weight HA in the range of 3.5-4.0×106 Da. The present invention also provides an efficient process for the purification of HA comprising treatment with silica gel then active carbon, and subsequent diafiltration with less volume of solvent.
